|
This schema declares XML elements for the DC elements and
|
|
26
|
DC element refinements from the http://purl.org/dc/terms/ namespace.
|
|
27
|
|
|
28
|
It reuses the complexType dc:SimpleLiteral, imported from the dc.xsd
|
|
29
|
schema, which permits simple element content, and makes the xml:lang
|
|
30
|
attribute available.
|
|
31
|
|
|
32
|
This complexType permits the derivation of other complexTypes
|
|
33
|
which would permit child elements.
|
|
34
|
|
|
35
|
XML elements corresponding to DC elements are declared as substitutable for the abstract element dc:any, and
|
|
36
|
XML elements corresponding to DC element refinements are defined as substitutable for the base elements
|
|
37
|
which they refine.
|
|
38
|
|
|
39
|
This means that the default type for all XML elements (i.e. corresponding to all DC elements and
|
|
40
|
element refinements) is dc:SimpleLiteral.
|
|
41
|
|
|
42
|
Encoding schemes are defined as complexTypes which are restrictions
|
|
43
|
of the dc:SimpleLiteral complexType. These complexTypes restrict
|
|
44
|
values to an appropriates syntax or format using data typing,
|
|
45
|
regular expressions, or enumerated lists.
|
|
46
|
|
|
47
|
In order to specify one of these encodings an xsi:type attribute must
|
|
48
|
be used in the instance document.
|
|
49
|
|
|
50
|
Also, note that one shortcoming of this approach is that any type can be
|
|
51
|
applied to any of the elements or refinements. There is no convenient way
|
|
52
|
to restrict types to specific elements using this approach.
|
|
53
|
|
|
54
|
Changes in 2008-02-11 version:
|
|
55
|
|
|
56
|
Add element declarations corresponding to 15 new dcterms URIs, and amend use of substitutionGroups.
|
|
57
|
|
|
58
|
Add compexType definitions corresponding to ISO639-3, RFC4646.
